Technical Field

The invention relates to the technical field of metal smelting, in particular to a side-blown converter wind blocking hole opening device.

Background

The side-blown converter is widely applied to the field of metal smelting of copper, nickel, lead, tin and the like, a plurality of primary air holes (the distance between the air holes is about 400mm generally) are uniformly and densely distributed on two sides of the side-blown converter, and oxygen-enriched air enters the converter through the air holes to participate in smelting reaction. In the production process, operations such as poking and opening of a primary air hole and the like are frequently required.

The air hole plugging operation of the side-blown converter mainly comprises the following 2 conditions:

1) when the process is normally produced, a certain air hole needs to be opened or blocked by allocation according to the condition in the furnace. Workers need to perform manual air hole plugging operation according to the furnace condition at ordinary times.

2) When the process is abnormal or overhauled, all wind eyes need to be quickly blocked within tens of seconds, and accidents such as melt backflow and the like can be caused if the blockage is not timely. The side-blown converter in the general case has more than 40 wind eyes, a factory must be equipped with a certain number of operators for waiting, and the wind eyes are prepared to be blocked in an emergency, which is also the reason that the side-blown converter operation must be equipped with a large number of personnel.

According to fig. 3, the operation space of the maintenance platform 7 is limited, if the operation platform is provided with the supporting structures such as the base, a large amount of operation space is occupied, especially when maintenance operation is carried out, the supporting structures such as the base can not effectively avoid the maintenance channel, and maintenance work can not be carried out smoothly. The side-blown converter wind eye opening and blocking device provided by the invention solves the technical problems, on one hand, the maintenance platform 7 does not need to be provided with any supporting structure, and on the other hand, based on the arrangement characteristics of the side-blown converter and the wind eyes, the lifting assembly drives the blocking mechanism 2 to swing up and down, so that the avoiding function of the blocking mechanism is realized, the maintenance operation of operators is facilitated, and the practicability is high.

It should be noted that all the structures capable of driving the blocking mechanism 2 to swing relative to the bracket assembly 1 may be the lifting assembly 3 mentioned in the above embodiments. For example: the lifting assembly 3 may be a mechanism with a telescopic function; or the lifting assembly can be connected with the side-blown converter supporting beam 5 in a sliding mode along the vertical direction, meanwhile, the lifting assembly is connected with the plugging mechanism 2 in a rotating mode and can move back and forth relative to the plugging mechanism 2, when the lifting assembly moves up and down along the vertical direction, the lifting assembly drives the end portion of the plugging mechanism 2 to swing up and down, and relative movement and rotation occur between the lifting assembly and the plugging mechanism 2.

In some embodiments, to achieve automatic opening of the occlusion mechanism 2, the occlusion mechanism 2 comprises an opening bracket 21, a first drive assembly 22, and an occlusion rod 24; the bracket component 1 and the lifting component 3 are respectively and rotationally connected with the unblocking bracket 21; the blocking rod 24 is connected with the first driving assembly 22; the first driving assembly 22 is installed on the unblocking bracket 21, and the first driving assembly 22 is configured to drive the blocking rod 24 to reciprocate relative to the unblocking bracket 21.

Facing to the direction of fig. 4, when the wind eye needs to be plugged, the first driving assembly 22 drives the plugging rod 24 to move leftward relative to the plugging opening bracket 21, as shown in fig. 5, until the plugging rod 24 enters the wind eye for a certain distance; on the contrary, when the blocking rod 24 needs to be withdrawn from the air hole, the first driving assembly 22 drives the blocking rod 24 to move rightwards to the initial position.

It should be noted that all the structures capable of driving the blocking rod 24 to reciprocate relative to the blocking bracket 21 may be the first driving assembly 22 mentioned in the above embodiments. For example: the first driving assembly 22 may be a linear motion mechanism such as an air cylinder, a hydraulic cylinder, a linear motor, etc., or a combination of a rotary motion mechanism such as a motor and a link mechanism to convert the rotary motion of the motor into a linear motion, and the principle thereof is similar to a crank-slider mechanism.

In addition, after the push rod 62 pushes up the rotating arm 242, the push rod 62 falls to the initial state to avoid causing obstruction to the next blocking operation of the blocking rod 24. The falling process can be manually operated, and the second driving assembly 61 can drive the ejector rod 62 to fall.
